Answer:
6 hours and 45 minutes
Step-by-step explanation:
First, convert 12 hours into minutes.
12*60=720
Convert 5 hours to minutes and add 15
5*60=300+15=315
Subtract 720 from 315.
720-315=405
Convert into hours and minutes.
405/60=6.75
0.75 of an hour is 45 minutes so the answer is 6 hours and 45 minutes.
Answer:
$36
Step-by-step explanation:
I = prt
I = 480(.015)(5)
I = 36
The addition property of equality is the idea we can add some number to both sides of an equation. You must add the same number to both sides to keep things balanced.
It's asking "what number can we add to both sides of this equation so that we isolate x?"
Think of 20+x as x+20. We can rearrange terms since adding in any order doesn't matter (eg: 2+3 = 3+2 = 5)
So we really have this equation: x+20 = 25
We can add -20 to both sides to cancel out the +20 on the left side
x+20 = 25
x+20+(-20) = 25+(-20) ...... add -20 to both sides
x = 5
This is the exact same as subtracting 20 from both sides. So 5 will go where x is, meaning that 20+x = 20+5 = 25
Namely, how much is 2 and 1/2 of 2 and 3/8 then, well is just their product, let's first convert them both from mixed to "improper" and proceed.
